I think the person they are talking about in the last episode(king carter or the the one they are afraid former crown prince might join hands with) is fl sister's lover,the one she ran away with.
Yes the face of the "bohemian" was revealed and they look exactly alike. Also, thank God tho he's obsessed with Alice (the sister) rather than becoming poor or having mistress but sadly, if he's to join hands with Johannes that'd be bad.
